Oil and gas exploration company ConocoPhillips has awarded a contract to engineering firm Subsea 7. It will supply the Barossa offshore project with infield flowlines and subsea umbilicals, risers and flowlines (SURF) infrastructure.
The Barossa offshore project is a gas field situated around 300km north of the Australian city of Darwin. Subsidiary company ConocoPhillips Australia Barossa operates the Barossa joint venture, owning a 37.5% interest in it. The other joint venture companies are SK E&S Australia with 37.5% and Santos Offshore with 25%.
ConocoPhillips also announced contracts with Aker Solutions and National Oilwell Varco Denmark to supply umbilicals and flexible risers, respectively.
The Barossa project contract includes a floating production storage and offloading (FPSO) facility, subsea wells and subsea production systems. A 260km pipeline will tie the development into the existing Bayu-Darwin Pipeline, flowing into Darwin.
ConocoPhillips Australia-West vice-president Steve Ovenden said: “Award of the SURF contracts is an important milestone for the project with contracts now in place for all the major facilities, following the earlier award of separate contracts for the FPSO facility, Gas Export Pipeline and Subsea Production System.
“Award of all major facility contracts has allowed us to significantly de-risk the project, providing increased confidence over our cost, schedule and execution plans heading into the Final Investment Decision.”
In October last year, ConocoPhillips signed an agreement to sell the subsidiaries that hold its Australia-West assets and operations to Santos for $1.39bn. It expects to close the cotnract in the first quarter of this year.
In the same year, ConocoPhillips awarded an engineering, procurement and construction and installation (EPCI) contract for the Barossa offshore project to Allseas Marine Contractors Australia.
